I have a trigger on a table with an XMLType column (in this case MSG_XML).
The trigger is to fire on the insert or update of the xml data.
It was created as
BEFORE INSERT OR UPDATE OF MSG_XML
When RE, TDM shows
BEFORE INSERT OR UPDATE OF MSG_XML,SYS_NC00002$
This gives an error when running the creation script as SYS_NC00002$ is unknown.
The TDM code is a correct representation of the data in ALL_TRIGGER_COLS,
however the pseudo coloumn added by Oracle should not be part of the SQL statement to create the trigger.
